This application is a division of my U. 8. Patent Number 2,10Q,080, issued Feb. 22, i938.

Furniture frame Furniture frames, particularly such as are bent into shape from a single piece of steel tubing, require after the bending a finishing treatment, consisting of polishing andpiating, which is all the more diflicult owing to the bulky state of the m frame.

The object of the present invention is to obtain furniture frames of this type whether made of steel tubing or similar material'wherein the finishing treatment will not present any partic- 15 ular difiiculty, and the invention consists in the provision of a frame composed of members each comprising a solid or tubular core and a facing for said core having the form of an enclosing, flexible metallic jacket.

This arrangement has in the first place the advantage that the core can be made of any suitable cheap material without regard to the appearance of the surface thereof, for instance,

rough steel tubing, the-necessary finishing treat- 25 ment, such as nickel or chromium plating, be-

ing applied to the flexible material forming the jacket. The latter may consist of a flexible pipe or hose 'of any well known kind and drawn over the core. As an alternative, the jacket may be 30 formed by winding or plaiting the material round the core. As a further alternative the jacket may be formed from long or short sleeves or rings which are mounted on the core.

with the foregoing objects in view several simil ple and practical embodiments of the invention are illustrated by way of example in the accompanying drawing, in which Fig. 1 represents a perspective view of a'chair made according to the invention: 40, Figs. 2 to 4 represent part elevations of'different forms of jackets for the core.

' prisin an shape of the frame, and a preformed flexible 30- 1 thereafter placing to the frame.

Fig. 1 shows the jacket b applied to a chair having aframe bent to shape from a steel tube c and having a seat a and back a.

The jacket may be of v a flexible metallic material, and may be nickel or chromium plated 5 or otherwise finished according to requirements.

The jacket may be formed by winding about the tube c a wire or the like. Fig. 2 shows such a winding composed of a wire d of semi-circular cross-section.

A further alternative is" shown in Fig. 3 wherein it will be seen that the jacket may be formed by metallic rings 9 with collars g and intervening grooves (1 which rings 0 are spaced apart by cylindrically arranged sleeves g Fig. 4 shows a sleeve covering it around the tube, which may consist of a plaited or woven wire or strip.

Having now particularly described and ascertained the nature of my said invention and in 2 what manner the same is to be performed, I declare that what I claim is:

1. A metal furniture frame having an unfinished metal core bent to the shape of the frame, and a continuous preformed flexible ornamental metal jacket placed around the exposed portions of thesaid core.

2; An ornamental metal furniture framecomunfinished metal core bent to the metallic plaited hose over the exposed portions of the frame to produce an ornamental surface.

:3. The method of' making ornamental metal furniture frames which consists in bending an unfinished metal core to desired shape, and

a flexible preformed ornamental metal jacket over exposed portions of said core to impart an ornamental metal finish ADOL'F BERGMANN.
